All Ford small block's except Cleveland, 2.3L OHC, all small ford six's, IIRC all Mopar small and Big blocks, all small block Chevy's all use the same fuel pump block off plate.
Big Block Chevy and Ford Cleveland use the elongated slender one.
Most EGR valves also use same flange as the fuel pump's so the fuel pump block off plate can double to block off a EGR valve mounting flange...of course you would only do that to mount a newer emmisions head on a older car.
